Sorry to bother, but with all the changes over the last few years, I feel a little lost now. I have AJE through AGEOD proper (before Matrix integration), and pretty much every other AGEOD game through GamersGate (from when AGEOD was part of Paradox). Just a few quick questions:

1. Is there a way to register my copy of Alea Jacta Est (I believe I also got a preorder bonus.. Spartacus I think?) with either the current website or Matrix/Slitherine?
2. Is there a way of registering any of my Gamersgate games with either the current webstore or Matrix/Slitherine?
3. If not, do the new patches work with the Gamersgate version of games?
4. Is there a way to upgrade from Rise of Prussia standard to Gold? Or would that just require a new purchase?
